This must be a simple thing to do but I am having problems.

I have a series of data that represent points in 3D space, which 
essentially form a deformed sphere. I thought that if I attached to 
each point a constant data value, say '1', then all I would have to do 
is to use IsoSurface to form a surface from all the points with the 
data value '1', .i.e. all points

Thus my data set of 'n' points looks like n lines of :
x y x 1
.... etc

In my case the number of points is formed from sampling a sphere 
at 3 deg intervals in theta and phi, yielding 120 x 60 = 7200 points.

Isosurface needs connections, so read the data set in using the 
data importer as a 120x60 regular grid with two fields. The first field 
I changed to 'locations', as a 3-vetcor field, and the second I 
changed to 'data' as a scalar field. 

I then hocked up the IMPORT module to the ISOSURFACE module 
and IMAGE. But I don't get anything out.

Is there something obvious I am doing wrong.

Any help would be appreciated.
